The NTSB's narrative final · quoted from the NTSB record

On the downwind leg of the traffic pattern for the joint civil/military airport, the instructor saw a Navy UH3H helicopter on the base leg to the same runway. The CTAF operator cautioned them about wake turbulence. The student asked if he should extend the downwind, but the instructor advised him to just stay above the helicopter's flight path. The instructor said that while turning to the base leg, they could see that the helicopter was still on the runway. On short final approach nearing the runway, the instructor announced their position on the CTAF. The helicopter remained on the runway, so the instructor advised the student to go around. At that point, the airplane was slightly past the runway threshold and the helicopter was about 2,500 feet down the 4,000-foot runway. The instructor stated that as the student initiated the go-around, the aircraft encountered some turbulence, and rolled 90 degrees to the right. The instructor then noticed the helicopter lifting off the ground. He took over the controls but had difficulty maintaining control of the aircraft. He stated that he attempted to fly out of the rotor wash, but didn't have sufficient altitude to maneuver safely. The airplane sank onto its right wing, bounced, and landed on the nose gear, which then collapsed. The airport is an auxiliary landing field for a naval air station. According to the airport facility directory, civil operations were permitted, but limited to daylight VFR conditions, and all aircraft must conform to the traffic pattern and CTAF advisories.
